FREE Essay on The Visual Perception of an Individual

[] Janice Holden suggested that Mrs. Davey's failure to see her body while ostensibly 'up on the ceiling' may have merely been an instance of "incomplete visual perception" rather than hallucination (Holden, "Heaven" 37). However, she notably cited Margot Grey's discovery that some out-of-body NDErs could not see their physical bodies even when they explicitly to see them (which is difficult to reconcile with the assumption that OBEs involve genuine perception of the physical area where the body would be), and in my reply I noted that in the majority of Oliver Fox's induced OBEs, Fox reported being unable to find his physical body lying on the bed despite explicitly looking for it there. I also noted that out-of-body discrepancies involving clearly perceptions—such as Robert Crookall's report of an OBEr who saw bars on his bedroom window that didn't exist—cannot be explained by selective attention to detail or preoccupation with something other than the location of one's physical body.

As already noted, though, one can believe that NDEs are not good evidence for survival or even that survival after death never happens without believing that "everything can be explained in purely material terms." David Chalmers, for instance, has recently defended a version of property dualism (in ) that denies that the mind can be explained in purely physical terms while also denying that the mind can exist independently of the brain (or some physical substrate); but the latter is a prerequisite for the sort of life after death Tart envisions.

But is there actually strong evidence of veridical paranormal perception in Ring and Cooper's sample of blind NDErs? One reason Fox questions the significance of this study is that those known to acquire sight for the first time, or reacquire it after a very long time, have difficulty making sense of their visual sensations. He notes the case of a 52-year-man who, after receiving corneal grafts, could not visually identify a lathe that he was otherwise well-acquainted with—by touch—unless he was given the opportunity to touch it. Continually frustrated at his inability to interpret his visual sensations, he eventually took his own life a full two years after the operation (Fox 225-226). By contrast, Ring and Cooper's blind NDErs are said to have "virtually immediately [gained] the ability to perceive accurately just such things as hospitals and streetlights with virtually no difficulty whatsoever" (226). While Ring and Cooper interpret this as evidence of a previously unknown sort of synesthetic perception 'transcending' normal human vision (224), Fox points out that more mundane sources—such as learning from mass media or NDE researchers that OBEs, tunnels, and lights are to be expected during near-death crises—might more satisfactorily explain the blind NDErs' testimonies (239). Irwin notes similar possibilities:

[These cases] may be inspired by accounts of other people's NDEs that have been widely disseminated in various forms of the media. That is, might a blind person have heard that people see certain things in a near-death encounter and unconsciously generated a fantasy that conformed to this belief?... [Blind NDErs might also] learn about what to expect in an afterlife from diverse sociocultural sources, and they may rely extensively on these expectations in generating a near-death fantasy.... Thus, the blind may commonly have a belief that they will suffer no visual affliction in an afterlife, and this belief may influence the content of NDEs in the blind (Irwin, "Mindsight" 112).

History Essay Visual Perception on Behance

As you might already be aware, the image on the retina is actually upside down from the actual image in the environment. At this stage of the perceptual process, this is not terribly important. The image has still not been perceived, and this visual information will be changed even more dramatically in the next step of the process.

Provide Multiple Means of Representation

From our earlier example, let's imagine that during your morning jog you focus your attention on the duck floating in the nearby pond. The duck represents the attended stimulus. During the next step of the perceptual process, the visual process will progress.

In print materials, the display of information is fixed and permanent. In properly prepared digital materials, the display of the same information is very malleable and customizable. For example, a call-out box of background information may be displayed in a different location, or enlarged, or emphasized by the use of color, or deleted entirely. Such malleability provides options for increasing the perceptual clarity and salience of information for a wide range of learners and adjustments for preferences of others. While these customizations are difficult with print materials. They are commonly available automatically in digital materials, though it cannot be assumed that because it is digital it is accessible as many digital materials are equally inaccessible. Educators and learners should work together to attain the best match of features to learning needs.
